Database Architecture

The Oracle Architecture is composed of several layers that work together to provide a robust, scalable database system. At the core is the Oracle Database, which relies on a multi-tiered architecture for storage and management of data. Key components include the Instance, which is made up of memory

Oracle的进程结构是Oracle数据库体系架构中的关键组成部分。用户端发出SQL命令后，Oracle的服务器进程负责接收并处理请求。通过内存区域进行精细的语法分析、编译和执行，最后将数据写入数据文件，并将数据库修改信息记录到日志文件。最终，执行结果被返回至客户端。

Oracle Database 12c Architecture is designed to enhance scalability and flexibility. It introduces multitenant architecture, allowing multiple databases (pluggable databases) to run within a single container. This enables better resource management and consolidation. Additionally, features like auto

Expert Oracle Database Architecture is a masterpiece created by Oracle's global engineers. This work showcases advanced techniques and insights into the design, implementation, and optimization of Oracle databases. The architecture emphasizes scalability, high availability, and efficient performance

Oracle数据库的逻辑结构是其核心组成部分，定义了数据如何在数据库中组织和管理。主要探讨了Oracle数据库体系结构的逻辑层面，包括表空间、段、数据块以及模式对象。 表空间（Tablespace）是Oracle数据库的最高级别的逻辑存储单元。每个表空间由一个或多个数据文件（Data Files）组成，数据文件的大小是数据块（Data Block）的整数倍。表空间的主要功能是为数据库对象提供存储空间，如数据表、索引和回滚段。例如，SYSTEM表空间是数据库创建时自动生成的，用于存储系统数据字典、程序单元等，同时也可存储用户数据。表空间的在线/离线、只读/读写状态可以通过SQL命令进行调整，但对

Toms Kyte的《Oracle9i&10g编程艺术》的第二版

数据库开发里的压箱底好书，Thomas Kyte的《Expert Oracle Database Architecture》真的挺值得一读。写得不啰嗦，讲得挺到位，从内存结构、事务到 SQL 优化，内容全、思路清晰。如果你碰到 Oracle 数据库卡顿或者写 PL/SQL 没方向，这本书能让你少踩多坑。

This book is aimed at those people who appreciate the choice but would also like some guidelines and practical implementation details on Oracle features and functions.
